OBJECTIVE:To observe the clinical efficacy of qianliexin combined with tamsulosin hydrochloride and finasteride in the treatment of elderly benign prostatic hyperplasia.METHODS:Ninety-four patients diagnosed as benign prostatic hyperplasia in our hospital during May.2012-Oct.2014 were selected and divided into observation group (48 cases) and control group (46 cases) according to even and odd admission number.Both groups received Finasteride tablet 5 mg,po,qd.Basedon this,control group was additionally given Tamsulosin hydrochloride sustained-release capsules 0.2 mg,po,qd;observation group was additionally given Qianliexin capsules 2.5 g,po,tid,on the basis of control group.Clinical efficacies of 2 groups were observed as well as IPSS,BS,IIEF-5 score,ultrasonic measurement indexes and TCM syndrome score before and after treatment.RESULTS:Clinical total response rate of observation group was 93.75％,which was significantly higher than 76.09％ of control group,with statistical significance (P＜0.05).Before treatment,there was no statistical significance in IPSS,BS,IIEF-5 score,ultrasonic measurement indexes and TCM syndrome score between 2 groups (P＞0.05).After treatment,IPSS and BS score,prostate volume (PV),residual urine(RU),each item score and total score of TCM syndrome were significantly decreased in 2 groups,while IIEF-5 score and Qmax were increased significantly;the observation group was significantly better than the control group,with statistical significance (P＜0.05).CONCLUSIONS:Qianliexin combined with tamsulosin hydrochloride and finasteride shows significant therapeutic effi cacy for elderly benign prostatic hyperplasia,and is helpful to improve prostate symptoms and TCM syndromes,reduce PV and RU,and improve sexual function.

Objective:To compare the efficacy and safety of bi-level positive airway pressure (BiPAP) ventilation and heated humidified high flow nasal cannula (HHHFNC) ventilation as initial respiratory support for premature infants with respiratory distress syndrome (RDS).Methods:From January 2019 to June 2021, premature infants [gestational age (GA) 28~35 weeks)] with grade Ⅰ to Ⅲ RDS admitted to Suining County People's Hospital were prospectively enrolled. The infants were randomly assigned into BiPAP group and HHHFNC group. The clinical characteristics, ventilation efficacy and complications were analyzed.Results:A total of 33 infants were in BiPAP group and 32 in HHHFNC group. No significant differences existed between the two groups in the following items: the frequency of apnea within 24 h of ventilation, FiO 2 and PaCO 2 at 24 h, the use of pulmonary surfactant (PS), the incidence of non-invasive ventilation failure within 72 h, non-invasive ventilation duration and the age achieving total enteral nutrition. HHHFNC group had lower score in premature infants pain profile (PIPP) than BiPAP group at 24 h of non-invasive ventilation [4 (3, 6) vs. 8 (6, 11), P<0.001]. No significant differences existed in nasal injury, pneumothorax, intraventricular hemorrhage, necrotizing enterocolitis, bronchopulmonary dysplasia and mortality rate between the two groups ( P>0.05). Conclusions:As the initial treatment for premature infants with grade Ⅰ to Ⅲ RDS, BiPAP and HHHFNC has similar rates of non-invasive ventilation failure within 72 h,non-invasive ventilation duration and adverse events. HHHFNC may ease the pain of the infants.

Objective:To investigate the effect of 4-octyl itaconate(4-OI)on transforming growth factor-β1(TGF-β1)-induced lung fibroblast-to-myofibroblast differentiation and related mechanisms.Methods:TGF-β1 was employed to induce the differentiation of the human embryonic lung fibroblast cell line MRC-5, and the effect of 4-OI on lung fibroblast-to-myofibroblast differentiation was examined.Cytotoxicity of 4-OI on MRC-5 cells was detected by the CCK-8 assay.Western blot was used to detect the protein levels of α-smooth muscle actin(α-SMA), collagen 1α1(COL1A1), fibronectin(FN), phosphorylated and total Smad2/3, and nuclear facor-E2 related factor 2(Nrf2).Real-time fluorescence quantitative PCR was used to detect the mRNA expression of α-SMA, COL1A1 and FN.Reactive oxygen species(ROS)levels were assessed by fluorescence microscopy and flow cytometry.Intracellular glutathione(GSH)concentrations were measured by spectrophotometry.Results:Pretreatment with 4-OI was able to inhibit TGF-β1-induced protein overexpression of α-SMA, COL1A1 and FN( F=122.8, 51.5, 27.2, all P<0.05), and increased mRNA levels( F=29.83, 51.62, 94.82, all P<0.01).In addition, 4-OI inhibited TGF-β1-mediated phosphorylation of Smad2/3 proteins in a dose-dependent manner( F=21.80, 36.69, P<0.01 for both).Pretreatment with 4-OI also reversed increased ROS levels( P<0.01)induced by TGF-β1 and enhanced GSH concentrations via disinhibition of TGF-β1( P<0.05).The inhibitory effect of TGF-β1 on Nrf2 expression was alleviated and Nrf2 nuclear translocation was uplifted by 4-OI pretreatment( P<0.05).After silencing Nrf2, 4-OI was unable to inhibit the increased protein expression of COL1A1 induced by TGF-β1, but was still able to inhibit the increased expression of α-SMA and FN protein induced by TGF-β1( P<0.05). Conclusions:4-OI could inhibit lung fibroblast-to-myofibroblast differentiation partially via Nrf 2 activation.

Objective To investigate the effects of glycosylphosphatidylinositol-anchored HDL-binding protein(GPIHBP1)on glioma growth and macrophage infiltration.Methods Initially,the expression of GPIHBP1 in glioma samples and macrophage infiltration were analyzed using TCGA data-base,and these bioinformatics results were validated in clinical tissue samples.A stable glioma cell line overexpressing GPIHBP1 was then established to further explore the effects of GPIHBP1 overexpression on glioma cell proliferation,apoptosis,migration,and invasion.Finally,the impact of GPIHBP1 over-expression on tumor growth and macrophage infiltration was verified through xenograft experiments.Results TCGA database analysis revealed that GPIHBP1 expression was higher in low-grade gliomas compared to normal tissues,while it was lower in high-grade gliomas.Additionally,the expression level of GPIHBP1 in low-grade gliomas was higher than in high-grade gliomas,which was confirmed by immu-nohistochemistry(IHC).Western blot analysis confirmed the successful construction of the GPIHBP1-overexpressing glioma cell line.CCK-8,flow cytometry,scratch and Transwell assays demonstrated that the proliferation,migration and invasion capabilities of the stable cell line were reduced compared to the control group.Xenograft experiments further showed that the tumor growth and macrophage infiltra-tion were decreased in the stable cell line.Conclusion The differential expression of GPIHBP1 in different grades of gliomas may be associated with tumor progression.Overexpression of GPIHBP1 can inhibit glioma growth,possibly by influencing the tumor microenvironment and promoting the polariza-tion of macrophages towards the antitumor M1 phenotype,thereby inhibiting glioma growth.

Objective:To design a new medication guidance tool for clinical intravenous therapy and nursing safety which covers all-dimensional information of intravenous therapy and nursing needs, and observe its application effects.Methods:(1) The treatment plans of common and frequently-occurring diseases in the priority departments of Class Ⅲ general hospitals in Jilin Province from January 2016 to December 2017 were retrospectively investigated and summarized to determine the index framework of intravenous therapy guidance tools. (2) The status quo survey, expert meeting and literature search were used to determine the content of the guidance tool and the drug information. (3) The expert consensus was used to determine the presentation of the guidance tool. (4) Totally 127 nurses in the departments were selected by convenient sampling for a non-contemporaneous controlled trial to compare the effects of the guidance tool after one month of application and nursing staff's level of knowledge about the risk of intravenous therapy.Results:(1) A guidance tool with 8 specialties, 73 treatment plans, and 326 commonly used drug information presented with specialties as an index and visualized signs was designed and developed, which covers relevant information such as requirements for infusion device materials, selection of infusion device, and requirements for inter-group tube flushing and sealing. (2) From May to June 2019, the nurses were tested before and after use, who were required to complete the specialist drug knowledge questionnaire within the specified time. The accuracy of the three dimensions of the physical and chemical properties of drugs, pharmacological effects, and safe use was 89.76%, 90.55%, and 95.27%, respectively, which were higher than that before use, and the difference was statistically significant ( P<0.05) . Conclusions:Based on the needs of clinical intravenous therapy and nursing safety medication, the novel guidance tool for intravenous therapy and safe medication nursing is designed and completed, which can effectively improve the nurses' ability to safely use intravenous medications and work efficiency and is worth promoting in clinical practice.

Objective:To explore the spatial autocorrelation and macro influencing factors of stroke mortality in Zhejiang Province in 2015-2020 and provide a scientific basis for stroke prevention and control strategy.Methods:The data on stroke death were obtained from Zhejiang Chronic Disease Surveillance System. The spatial distribution of stroke mortality was explored by mapping and spatial autocorrelation analysis. The spatial panel model analyzed the correlation between stroke mortality and socioeconomic and healthcare factors.Results:From 2015 to 2020, the average stroke mortality was 68.38/100 thousand. The standard mortality of stroke was high in the areas of east and low in the west, high in the south and low in the north. Moreover, positive spatial autocorrelation was observed (Moran's I=0.274-0.390, P<0.001). Standard mortality of stroke was negatively associated with per capita gross domestic product (GDP) ( β=-0.370, P<0.001), per capita health expenditure ( β=-0.116, P=0.021), number of beds per thousand population ( β=-0.161, P=0.030). Standard mortality of ischemic stroke was negatively associated with per capita GDP ( β=-0.310, P=0.002) and standard management rate of hypertension ( β=-0.462, P=0.011). Standard mortality of hemorrhagic stroke was negatively associated with per capita GDP ( β=-0.481, P<0.001), per capita health expenditure ( β=-0.184, P=0.001), number of beds per thousand population ( β=-0.288, P=0.001) and standard management rate of hypertension ( β=-0.336, P=0.029). Conclusions:A positive spatial correlation existed between stroke mortality in Zhejiang Province in 2015-2020. We must focus more on preventing and controlling strokes in relatively backward economic areas. Moreover, to reduce the mortality of stroke, increasing the investment of government medical and health funds, optimizing the allocation of medical resources, and improving the standard management rate of hypertension are important measures.

Leucine rich glioma inactivated 1 (LGI1) is a protein which is identified as the target involving in autoimmune encephalitis. Seizures and cognitive declines are two main symptoms of LGI1-antibody encephalitis. However, autonomic dysfunction symptoms are not prominent as seizures and cognitive defection and are easily overlooked by physicians. We reported a case with LGI1-antibody encephalitis whose onset symptoms were autonomic dysfunction including sweating, orthostatic hypotension. The features of this case was described in detail and the related literatures were reviewed in order to enhance the knowledge of the disease.

Objective:To evaluate the effect of comprehensive intervention combined with clinical preventive services and lifestyle adjustment on high-risk populations of cardiovascular disease.Methods:In 2015, 4 towns (streets) in Tongxiang City, of Zhejiang Province including Heshan Town, Longxiang Street, Wutong Street, and Fengming Street, were selected by using the typical sampling. The towns (streets) were allocated to the intervention group (Heshan Town and Longxiang Street) and the control group (Wutong Street and Fengming Street) by using the cluster random sampling. In each town (street), hypertension patients aged 50 to 74 years old who were taking community medicine management and with a 10-year cardiovascular disease risk ≥10% were recruited as subjects. There were 1 823 subjects in the intervention group and 1 883 in the control group. The intervention group was given a 1-year comprehensive intervention combining clinical preventive services and lifestyle adjustment, while the control group received routine chronic disease management. After the intervention, the final questionnaire investigation was conducted and health physical examination data were obtained. The death, acute coronary heart disease events and stroke incidence were the primary outcomes, and cardiovascular disease-related knowledge and behavior, clinical preventive services utilization, physical changes, blood fat index and 10-year cardiovascular disease risk were the secondary outcomes. The difference-in-difference model was used to evaluate the effects of interventions.Results:The age of subjects in the intervention and control group was (68.76±3.75) and (67.90±4.56) years old, respectively. After 1-year intervention, the incidence of mortality, acute coronary events and stroke in intervention group was 1.65% (30 cases), 0.27% (5 cases) and 2.69% (49 cases), respectively, which showed no statistical difference compared to the control group [1.33% (25 cases), 0.32% (6 cases) and 2.07% (39 cases)]. After adjusting for the age, gender, education, marital status, self-assessed family income level and situation of taking antihypertensive drugs, the difference-in-difference model showed that the body mass index and diastolic blood pressure in the intervention group decreased by 0.33 kg/m 2 and 1.49 mmHg (1 mmHg=0.133 kPa). Compared with the control group, daily vegetable consumption proportion, the awareness rates of aspirin, stains, salt intake, and oil intake increased by 4.76%, 26.22%, 29.56%, 10.80%, and 15.17%, respectively ( P<0.05). Conclusion:After the 1-year comprehensive intervention, there was no significant change in primary outcomes among high-risk populations of cardiovascular disease. In secondary outcomes, body mass index and diastolic blood pressure declined and cardiovascular disease-related knowledge awareness increased.
